- notched portions 13 and flange protrusion portions 14 are formed on this flange 10 .
- the notched portions 13 are die cut holes occurring for the formation of the panel engagement portions 11 .
- the notched portions 13 are used at the time of easy disassembly of the grommet-equipped connector 1 in the present invention (easy disassembly will be described later).
- the flange protrusion portions 14 are formed as substantially rectangular protruding portions constituting the same surface as the flange 10 and such that the end portion of the flange 10 is further protruded outward (in other words, formed as spatula form protruding portions). These flange protrusion portions 14 are formed in such a manner as to be arranged on the lower side arc portion in FIG. 1 . Moreover, two flange protrusion portions 14 are formed so as to be symmetric with respect to the central axis (not shown) in the vertical direction (The number is an example. In the case of portions described below, the number may be, for example, one).
- the pair of flange protrusion portions 14 are formed in a shape inserted in a later-described deep groove portion 29 of the grommet 4 in a non-through manner. Moreover, the pair of flange protrusion portions 14 are formed in a shape where the protrusion ends are situated outside virtual lines L (on the right and the left in FIG. 1 ) (the virtual lines L are lines drawn straightly in the vertical direction along the above-mentioned straight walls).
- the pair of flange protrusion portions 14 which have the shape where the protrusion ends are situated outside the virtual lines L as described above are formed as portions capable of being guided by a later-described flange fitting groove 28 of the grommet 4 and portions that prevent detachment from the flange fitting groove 28 .
- Such pairs of flange protrusion portions 14 are formed also as one component of a mounting detection portion 15 . Moreover, they are formed also as mis-assembly preventing portions when the connector 3 is upside down.
- the pair of flange protrusion portions 14 serve as work start portions on the side of the connector 3 in the work of mounting the grommet 4 on the connector 3 although this will become apparent in the description that follows (it can be said that one or more than one flange protrusion portion 14 is formed in accordance with the work start portion).

- the direction changing tubular portion 18 is continuously formed on the rear end of the panel contact portion 17 .
- the direction changing tubular portion 18 is formed so that the electric wire bundle 2 can be made to face down after drawn out from the connector 3 .
- the direction changing tubular portion 18 is formed so that the drawing direction of the electric wire bundle 2 is toward the protruding side of the pair of flange protrusion portions 14 .
- the drawing direction of the electric wire bundle 2 is made downward (this is because the work is difficult to perform if the electric wire bundle 2 is drawn out in such a manner as to pass a portion of the grommet 4 that is mounted last, that is, an upper portion in the figure in the present embodiment).
- the direction changing tubular portion 18 is formed so as to face downward in the present embodiment in order to facilitate the mounting of the grommet 4 , this is an example. That is, unless it faces upward, the electric wire bundle 2 may be drawn out, for example, in the horizontal direction.

- the deep groove portion 29 as one characteristic portion of the present invention is formed.
- the deep groove portion 29 is disposed in accordance with the positions of the pair of flange protrusion portions 14 of the flange 10 .
- the deep groove portion 29 is formed as a fitting portion for the pair of flange protrusion portions 14 .
- the deep groove portion 29 is formed as a non-through concave portion that is deeper in groove depth than the flange fitting groove 28 .
- the deep groove portion 29 is formed as a concave having the same groove width as that of the flange fitting groove 28 (the groove width is an example, and the shape may be, for example, saclike as in the second embodiment described later).
- the deep groove portion 29 is formed so that the pair of flange protrusion portions 14 can be handled by one concave.
- the base portion 21 inside which the deep groove portion 29 is present is formed in a shape where an expanding portion is partially present when viewed from the outside.
- the deep groove portion 29 is formed as one component of the mounting detection portion 15 .
- the insertion position is an example, and it may be performed to directly insert into the arc portion which is a lower position, that is, the flange fitting groove 28 where the deep groove portion 29 is present.
- the condition is the same as that shown in FIG. 4 and FIG. 5 .).
- it is performed to pull up the grommet 4 from the inserted condition of FIG. 3 .
- the protrusion ends of the pair of flange protrusion portions 14 are guided by the flange fitting groove 28 (the protrusion ends are guided so that the grommet 4 is smoothly slid without detached).
- the elliptic attachment hole 8 that is long in the vertical direction is formed.
- the part of the connector 3 of the grommet-equipped connector 1 is inserted into the attachment hole 8 , the panel engagement portions 11 are engaged with the attachment hole 8 as shown in FIG. 9 and the flexible elastic portion 20 of the panel contact portion 17 is pressed against the edge portion 12 of the attachment hole 8 so as to intimately contacts, whereby the attachment of the grommet-equipped connector 1 is completed.
- the flexible elastic portion 20 is elastically deformed to be pressed against the edge portion 12 as shown in FIG. 10 and at this time, the pressed portion (elastically deformed portion) becomes watertight, waterproofness is sufficiently secured.
- the use of the pair of finger pressing portions 27 of the grommet 4 is effective.
- the finger pressing portions 27 will be described later with reference to FIGS. 11A and 11B .
- the four thin portions 26 are formed on the rear surface 24 of the base portion 21 in the panel contact portion 17 .
- These thin portions 26 are formed in such a manner as to be disposed in accordance with the positions of the panel engagement portions 11 in the connector 3 .
- they are formed in a shape that concaves a wall 30 between the rear surface 24 and the flange fitting groove 28 in the direction of the wall thickness.
- the thin portions 26 having such a shape are formed as portions for easily detaching (easily disassembling) the grommet-equipped connector 1 from the attachment hole 8 of the panel 7 .
- an advantage is produced that the workability at the time of the mounting of the grommet 4 can be improved to be higher than before. Moreover, according to the grommet-equipped connector 1 of the present invention, an advantage is also produced that the detection related to the normal mounting of the grommet 4 can be performed with a simple structure.
- FIGS. 11A and 11B are views of a grommet-equipped connector as another example. Components basically the same as those of the above-described first embodiment are denoted by the same reference numerals and detailed descriptions thereof are omitted.
- the grommet-equipped connector 1 of the second embodiment is different from that of the first embodiment in part of the grommet 4 .
- the second embodiment is different from the first embodiment in that the deep groove portion 29 formed inside the panel contact portion 17 is saclike and the internal space of the deep groove portion 29 spreads rearward.
- the connector 3 by housing the connector 3 obliquely with respect to the large saclike deep groove portion 29 in the internal space and pressing the pair of finger pressing portions 27 with the worker's finger lastly, the connector 3 can be easily moved from the obliquely housed condition to the normal mounting position. Therefore, it is needless to say that the attachment of the grommet-equipped connector 1 to the attachment hole 8 of the panel 7 (see FIG. 7 ) is not obstructed.
- FIGS. 12A and 12B is views of a grommet-equipped connector of the present invention as another example.
- Components basically the same as those of the above-described first and second embodiments are denoted by the same reference numerals and detailed descriptions thereof are omitted.
- the grommet-equipped connector 1 of the third embodiment is different from that of the first embodiment in part of the connector 3 and part of the grommet 4 .
- the third embodiment is different from the first embodiment in that the flange 10 in the connector frame 6 is formed in an elastic umbrella shape and that the shape of the panel contact portion 17 is simplified by such an elastic-umbrella-shaped flange 10 . It is needless to say that the pressing force can be sufficiently secured at the elastic-umbrella-shaped flange 10 in the third embodiment even though the shape of the panel contact portion 17 is simplified.
- the present invention may be structured without inclusion of the detection structure related to the normal mounting of the grommet 4 . That is, it is necessary only that the connector 3 be provided where the flange protrusion portions 14 are formed on the flange 10 and these flange protrusion portions 14 are guided by the flange fitting groove 28 of the grommet 4 .
- a grommet-equipped connector including: a connector that includes: a panel engagement portion configured to be engaged with an attachment hole of a panel; and an annular flange configured to face an edge portion of the attachment hole; and a grommet that includes a panel contact portion configured to be fitted so as to cover the flange and intimately contact the edge portion, wherein a flange fitting groove in which the flange is inserted over an entire perimeter is formed inside the panel contact portion; and wherein the flange has a flange protrusion portion protruding outward and guided by the flange fitting groove.

- the formation of the flange protrusion portion enables simplification of the structure of the grommet itself.
- an advantage is produced in that the workability at the time of the mounting of the grommet can be improved.
- the flange fitting groove has a deep groove portion of a concave shape or a saclike shape that is deeper in groove depth than the flange fitting groove, and the flange protrusion portion being inserted into the deep groove portion in a non-through manner.
- the mounting of the grommet on the connector can be performed to the last.
- the flange protrusion portion is not inserted in the deep groove portion (in the condition where the flange protrusion portion is situated in the flange fitting groove)
- the relative positional relationship between the connector and the grommet is shifted by the protruding length of the flange protrusion portion, and as a consequence, the mounting of the grommet is restricted and the mounting cannot be performed to the last.
- the detection related to the normal mounting of the grommet can be performed with a simple structure.
- the panel contact portion has a thin portion disposed in correspondence with a position of the panel engagement portion and having a shape that concaves a wall in a direction of a wall thickness.
- disassembly of the connector from the panel can be easily performed. Specifically, by inserting a jig such as a flat-head screwdriver into the thin portion and applying force so that the thin portion is broken through, the panel engagement portion in a state of being engaged with the attachment hole of the panel can be easily disengaged.
- a jig such as a flat-head screwdriver
- the easy disassembly of the grommet-equipped connector from the panel can be performed.
- the deep groove portion is formed in the saclike shape, and a finger pressing portion capable of pressing the connector with a finger over the panel contact portion is formed on the panel contact portion.
- the mounting of the grommet on the connector can be easily performed without pulling with a large force.
- the mounting of the remaining part of the grommet thereafter can be performed with a comparatively small force (can be performed without large pulling up).
- the movement of the connector to the normal mounting position can be easily performed. Consequently, the mounting of the grommet can be easily performed.
- the workability at the time of the mounting of the grommet can be further improved.
- the grommet has a tubular electric wire housing portion for housing an electric wire bundle drawn out from the connector, the tubular electric wire housing portion being provided continuously with the panel contact portion, and the electric wire housing portion has a direction changing tubular portion that directs a drawing direction of the electric wire bundle toward a protruding direction of the flange protruding portion.
- the work on the part on which this mounting is performed last can be easily performed. This is because the drawing direction of the electric wire bundle becomes a direction not passing the above-mentioned last-mounted part. That is, this is because the drawn-out part of the electric wire bundle comes not to obstruct the mounting work.
- the drawing direction of the electric wire bundle is toward the protruding direction of the flange protrusion portion, it is needless to say that any direction is sufficiently effective as long as it is a direction not passing the above-mentioned last-mounted part.
- the workability at the time of the mounting of the grommet can be further improved.
- a connector includes an annular flange configured to face an edge portion of an attachment hole of a panel, an entire perimeter of the flange is configured to be inserted in and covered by a flange fitting groove of a panel contact portion of a grommet intimately contacting the edge portion, and the flange has a flange protrusion portion that protrudes outward and is configured to be guided by the flange fitting groove.
- the flange protrusion portion in mounting the grommet on the connector, the flange protrusion portion is guided by the flange fitting groove.
- the flange protruding portion By the formation of the flange protruding portion, detachment from the flange fitting groove never occurs and the flange protrusion portion is guided by the flange fitting groove, so that the mounting of the grommet can be smoothly performed.
- the formation of the flange protrusion portion enables simplification of the structure of the grommet itself.
- an advantage is produced in that the workability at the time of the mounting of the grommet can be improved.
